The 1976 evening peak timetable included 28 tph from Charing Cross, but of
these 3 crossed at Spa Road and ran via Greenwich, and 3 crossed to the Slow
Line at North Kent East, so only 22 ran on the Fast Line at Tanners Hill
Junction.6 of these ran via the spur. On the Up Fast there were 22 trains
through Tanners Hill Junction (these had to cross the 6 down via the spur),
with another 3 coming via Greenwich and crossing at Spa Road.

But let's not forget that the much vaunted "completely rewritten and
improved" 1976 timetable was a complete cock-up, and it wasn't until the
1980s and the introduction of the 66 minute hour that things really
sorted themselves out.

28tph through the 2 track section just didn't work.


Was that the main problem? I ask because the morning timetable didn't
go 66-minute when the evening timetable did, and I wondered if it was
because the Tanner's Hill Spur is much more useful in the
"up" (downhill) direction (not crossing the track it doesn't join),
with more flat crossing movements needed in the evening for the same
number of services.
